IPC: G05B19/423
Filed: 1983-02-08
Abstract: PURPOSE:To shorten the instruction time and to attain precise instruction by attaching an optical beam generator and a photodetective sensor to a handle of a playback type industrial robot and a machine tool respectively and moving these parts along an optical axis to store a positional point. CONSTITUTION:The optical beam generator 17 is attached to the front of the machine tool 1 and the photodetective sensor 19 is fitted to the handle 21 of the working robot 5. A work 3 is positioned on a point A and the optical axis is adjusted so that an optical beam can be sensed. When the robot 5 is made forward by xmm. and the optical sensor senses light, the sensed point is stored. If the sensor does not sense the light, the robot 5 is made forward vertically by ymm., and when the optical beam is sensed, the point is stored. If not sensed, the robot 5 is moved by -ymm.. When not sensed, the point is stored and the robot 5 is made forward by xmm. again and a position sensing the optical beam is stored. When the robot 5 is made forward up to a point B, the program is shifted to the succeeding processing.
